You get the IP-address of the running machine by issuing docker inspect dc1 | grep IPAddress and the root user'spassword as well as other passwords by running docker logs dc1 2>&1 | head -3. You should then be able to log in with SSH.

The problem is that the port range 1024 and upwards are used for dynamic RPC-calls, luckily Samba goes through them inorder, so the first 20 or so should suffice for testing purposes. Windows complains otherwise that "The RPC server isunavailable". It's also possible to eliminate long command line parameters by using $(for port in $(seq 135 139); do
echo -n "-p $port:$port "; done;) instead.
